Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter with a fertilizer application in which a fertilizer application device is mounted above a planting mechanism for taking out and planting seedlings from the lower end of a seedling stand in the seedling planting device.

[0002]

2. Description of the Related Art In the rice transplanter with a fertilizer application described above, conventionally, as shown in, for example, Japanese Utility Model Laid-Open No. 3-22616, the fertilizer application is arranged in a fixed position by a support frame erected from a planting transmission case. It was configured to do.

[0003]

However, in the above-mentioned conventional structure, since a plurality of tall fertilizer application devices are arranged above the seedling planting site for each row, for example, work in a certain field can be performed. At the time of completion, when taking out the placed seedlings that are slightly left on the seedling stand, this fertilizer application would be an obstacle and would make the work difficult to perform, and there was room for improvement. The present invention aims to eliminate the above-mentioned problems.

[0004]

According to a characteristic configuration of the present invention, in the rice transplanter with a fertilizer application described at the beginning, the fertilizer application work on the lower side is performed on a support rail erected from a frame of the seedling planter. It is configured to support up and down position changeable between a position and a position retracted upward, and the other end of the wire whose one end is fixed to a support rail is connected to the fertilizer application device, and a movable pulley that acts on the wire, The urging mechanism is configured to urge the fertilizer application to move upward in the upward direction.

[0005]

[Function] A fertilizer application device can be installed at a work position above the planting mechanism to effectively perform fertilizer application, and when a small amount of the remaining seedlings is taken out from the seedling stand after the planting work is completed, fertilizer application is performed. By moving the device upward along the support rail to a higher position, the outer side of the lower end of the seedling stand is largely opened, and the seedling removal work can be performed easily. Further, at this time, it is necessary to move a plurality of fertilizer applicators having a large total weight upward for a large stroke, but the urging mechanism lifts and urges the fertilizer upward, so that the lifting operation force is small. Finished, work can be done easily. Moreover, since the urging mechanism is configured to move the moving pulley, the operation stroke of the urging mechanism is half the movement stroke of the fertilizer application device, and a small size can be used.

[0006]

[Effects of the Invention] Therefore, the fertilizer supply is set as close as possible to the seedling planting place, and the working position of the fertilizer application is set at a position close to the planting mechanism in order to minimize the delay time required for downflow guidance. Although it can be freely operated, it can be evacuated to a place where it does not interfere with the work of removing the remaining seedlings on the seedling stand, and the seedling removal work can be performed efficiently. Furthermore, the heavy fertilizer application can be moved lightly and the operability is good, and the rational configuration allows the urging mechanism to be small while increasing the evacuation movement stroke of the fertilizer operation. Since the required operation stroke of the urging mechanism becomes small, there is also an advantage that the change in urging force before and after the movement can be made small.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rice transplanter equipped with a fertilizer application device, which is equipped with a fertilizer application device for feeding fertilizer to a field along with planting of seedlings.

[0002]

2. Description of the Related Art As a fertilizer application apparatus as described above, a fertilizer storage hopper, a feeding section for feeding fertilizer from the fertilizer storage hopper, a feeding section for feeding the fertilizer to the field, and a guide for guiding the fertilizer fed out from the feeding section to the feeding section. Some are configured with a pipe, and there are many rice transplanters with a fertilizer application device that fixes this fertilizer application device at a predetermined position.

[0003]

In the fertilizer applicator of the rice transplanter with the fertilizer applicator as described above, since other devices are often disposed near the fertilizer storage hopper and the feeding part, the fertilizer storage hopper and It may be difficult to perform maintenance work on the feeding section and other devices near this. It is an object of the present invention to facilitate maintenance work of a fertilizer storage hopper and a feeding section of a fertilizer application device and other devices in the vicinity in a rice transplanter equipped with a fertilizer application device.

[0004]

A feature of the present invention is that a rice transplanter with a fertilizer application device is constructed as follows. A fertilizer storage hopper, a feeding section for feeding fertilizer from the fertilizer storage hopper, a feeding section for feeding the fertilizer to the field, and a guide pipe for guiding the fertilizer fed from the feeding section to the feeding section are provided for planting seedlings. A fertilizer applicator that feeds fertilizer to the field is constructed, and the outlet of the feeding part is shaped like a trumpet that spreads downward, and the outlet can be connected and separated so that it covers the inlet end of the guide pipe from above. The fertilizer storage hopper and the feeding section are arranged in the working position over the lower working position where the discharge port is connected to the inlet end of the guide pipe and the non-working position separated upward from the working position. When the discharge port of the feeding portion is connected to the inlet end portion of the guide pipe, the guide member is movably supported in a maintained state. Come out the mouth and the guide pipe,
It is set so as to be located near the guide member in a side view of the machine body.

[0005]

[I] According to the feature of claim 1, it is possible to move the fertilizer storage hopper and the feeding portion located at the work position in the fertilizer application to the non-work position separated from the work position along the guide member. With this, by separating the fertilizer storage hopper and the feeding unit from the working position to the non-working position, maintenance work of the fertilizer storage hopper and the feeding unit can be performed without being disturbed by other devices arranged near the working position. It can be done easily. For maintenance work of other devices located near the work position,
It can be easily performed without being disturbed by the fertilizer storage hopper and the feeding section.

When moving the fertilizer storage hopper and the feeding unit between the working position and the non-working position, the fertilizer storage hopper and the feeding unit can be moved and operated while maintaining the posture at the working position. When moving the fertilizer storage hopper and the feeding unit, the fertilizer in the fertilizer storage hopper and the feeding unit does not spill, and it is not necessary to take out the fertilizer from the fertilizer storage hopper and the feeding unit for the moving operation.

[II] According to the feature of claim 1, since the fertilizer storage hopper and the feeding unit can be moved in the vertical direction between the lower working position and the upper non-working position, the moving operation to the non-working position can be performed. , The fertilizer storage hopper and the feeding part do not largely extend laterally from the range of the rice transplanter equipped with a fertilizer application device. As a result, even in a relatively narrow place such as a barn, the fertilizer storage hopper and the feeding unit can be moved to the upper non-working position without any trouble.

[III] In a fertilizer application apparatus comprising a fertilizer storage hopper, a feeding section, a guide pipe and a feeding section, the feeding section for feeding the fertilizer to the field is arranged at a relatively lower portion near the field, and the fertilizer storage hopper is provided. Further, the guide pipe is relatively distant from the feeding portion, and the guide pipe is formed to be relatively long so as to connect the feeding portion and the feeding portion. Therefore, if the feeding part and the guide pipe are configured to be movable to the non-working position together with the fertilizer storage hopper and the feeding part, the moving structure of the fertilizer application becomes large. According to the feature of claim 1, leaving the feeding portion and the guide pipe on the working position side,
Since the fertilizer storage hopper and the feeding section are configured to be freely movable along the guide member from the working position to the non-working position, the moving structure of the fertilizer applying apparatus does not become a large scale.

[IV] According to the feature of claim 1, when the fertilizer storage hopper and the feeding unit are moved to the working position side and the discharge port is connected to the inlet end of the guide pipe,
Even if the position of the outlet and the position of the inlet end of the guide pipe are slightly displaced, the inlet end of the guide pipe is guided by the outlet that spreads like a trumpet, and the outlet and the inlet end of the guide pipe are separated from each other. Connected accurately.

Further, when the outlet of the feeding portion is connected to the inlet end of the guide pipe, the outlet and the guide pipe are set so as to be located in the vicinity of the guide member in a side view of the machine body. Since the distance between the outlet of the feeding section supported by the guide member and the guide member itself is small in the side view of the machine, even if the moving operation of the fertilizer storage hopper and the feeding section is repeated, the outlet of the machine is seen in the side view. Does not fluctuate, and when the fertilizer storage hopper and the feeding part are moved to the work position, the discharge port is always at approximately the same position (the position connected to the inlet end of the guide pipe) in side view of the machine. .
Thus, when the fertilizer storage hopper and the feeding unit are moved to the work position side, the discharge port is accurately connected to the inlet end of the guide pipe.

[V] At the working position of the fertilizer storage hopper and the feeding part, the outlet of which is connected to the inlet end of the guide pipe, the inlet end of the guide pipe is covered from the upper side by the trumpet-shaped outlet that spreads downward. Since the discharge port and the inlet end of the guide pipe are engaged with each other, the discharge port and the inlet end of the guide pipe are disengaged at the working position of the fertilizer storage hopper and the feeding unit. To stay connected. As a result, there is no need for a special connecting member or the like for maintaining the connection between the outlet and the inlet end of the guide pipe. At the working position of the fertilizer storage hopper and feeding part, the trumpet-shaped outlet that spreads downward is located above the inlet end of the guide pipe, so that rainwater, etc. do not enter the guide pipe. .

[0012]

According to the first aspect of the present invention, in the rice transplanter with the fertilizer application device, the fertilizer storage hopper and the feeding unit located at the working position can be moved to the non-working position away from the working position. , The maintenance work of the fertilizer storage hopper and feeding section, and other devices arranged near the work position can be easily performed, and the workability of the rice transplanter with the fertilizer application device can be improved. It was When moving the fertilizer storage hopper and the feeding unit between the working position and the non-working position, the fertilizer in the fertilizer storage hopper and the feeding unit does not fall down. There is no need to take the fertilizer out of the part, there is no waste of the fertilizer, and the spilled fertilizer is prevented from rusting due to the adhered metal parts.

By constructing the fertilizer storage hopper and the feeding section so as to be movable in the vertical direction between the lower working position and the upper non-working position, the fertilizer storing hopper can be used even in a relatively narrow space such as a barn. Further, since the feeding section can be moved to the non-working position without any trouble, the workability of the rice transplanter with the fertilizer application can be further improved.

By leaving the feeding section and the guide pipe on the working position side and arranging the fertilizer storage hopper and the feeding section so as to be movable from the working position to the non-working position, the moving structure of the fertilizer applicator is large. However, in the working position of the fertilizer storage hopper and the feeding part, there is no need for a special connecting member or the like for maintaining the connection state between the discharge port and the inlet end of the guide pipe. It is advantageous in terms.

A point at which the inlet end of the guide pipe is guided by the trumpet-like spreading outlet and connected to the outlet, and the side surface of the machine body when the fertilizer storage hopper and the feeding portion are moved to the working position side. When the fertilizer storage hopper and the feeding section are moved to the working position side, the discharge port and the inlet end of the guide pipe can be easily and easily connected because the discharge port always comes to the substantially same position without swinging. It becomes possible to do it accurately, and it becomes easy to operate. At the working position of the fertilizer storage hopper and feeding section, rainwater does not enter into the guide pipe due to the trumpet-shaped outlet, so that fertilizer may adhere to the guide pipe due to rainwater or the fertilizer may solidify. The clogging phenomenon is prevented in advance.
